SHAFT SUPPORT.

Application filed July 26, 1917.

To all whom it may concern:

Be it known that I, WILLIAM F. HA1:- nmeToN, a subject of the King ofGreat Britain and Ireland, residing at Toledo, in

5 the county of-Lucas and State of Ohio,

have invented certain new and useful Improvements in Shaft Supports, ofwhich I declare the following to be a full, clear,

and exact description.

in shaft supports and particularly to im provements in the mounting forthe fan shaft of an internal combustion engine.

The object of my invention is to provide an improved fan shaft mountingfor automobile engines, which is automatically adjustable to keep thefan belt tight.

A further object of my invention is to provide an improved mounting forthe fan shaft of an internal combustion engine, which mounting willpermit of the vertical movement of the fan shaft, but will preventswinging of the same from side to side.

A further object of my invention is to provide a fan shaft mounting,which is automatically adjustable to tighten the-belt, and which isprovided with improved means for lubricating the same.

A. further object of my invention is to provide an improved mounting fora fan shaft, which is simple in construction and can be quickly andreadily manufactured and assembled.

' Further objects, and objects relating to economies of manufacture anddetails of construction, will definitely appear from the detaileddescription to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. My invention is clearlydefined and pointed out in the appended claims.

A structure constituting a preferred em bodiment of my invention isillustrated in the accompanying drawing, forming a part of thisspecification, in Which Figure I is a view in side elevation of Thisinvention relates to improvements Serial No. 182,863.

an internal combustion engine, having a fan shaft mounted in accordancewith my invention, a part of said mounting being shown in section inorder to show the con struction more clearly.

Figure II is an enlarged, detail, fragmentary view, partly in section,showing the fan shaft mounting in greater detail.

Figure III is a detail, fragmentary, sectional view taken substantiallyon the line III-III of Figure IIand Figure IV is a fragmentary. detailview taken substan tially on the line IV-IV of Figure III.

In the drawings, similar reference numerals refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawings, the internal combustionengine 10 drives the shaft 11 on which the pulley 12 is mounted. An arm13 extends upward-- 1y from the head of said engine and is provided witha vertical passage 14: therein, in which the post 16 is slidablymounted, and said arm also has a vertical face 15 below the portion inwhich the passage 14 is provided. The shaft 17 extends horizontally fromthe lower end of the vertical post 16, in one direction, and in the op--posite direction from said post, there is provided the head 18 l'iavinga vertical face which is adapted to engage with and slide up and downonthe vertical face 15 of the 13. The horizontal passage 20 is providedin the shaft 17, being closed at one end by the plug 19, and connectswith the passage 21 in the post 16, as clearly ap pears from Figure IIof the drawing.

Compression spring 22 is provided on the post 16, between the arm 13 andthe head on said. post, so as to normally force the post upward in thepassage 14 in said arm. An oil cup 24 is carried on the upper end ofsaid post, and lubricant feeds through the passage 21 and the passage 20and through an opening provided in the sleeve 25, which is fixed on theshaft 17, so as to lubricate the pulley 26, which is journaled on saidsleeve 25. The sleeve 25 is held on the shaft by means of the nut 27threaded on the end of said shaft and said pulley 26 is provided with arearwardly extending sleeve 28, having an annular flange 29, to whichthe fan blades 30 are secured in a suitable manner. The pulleys 12 and26 ar connected by the fan belt 31, so that the fan is driven by saidbelt from the shaft 11.

From the description of the parts given above, the operation of mydevice should be very readily understood. The shaft 17, upon which thefan is journaled, is subject to vertical movement, due to the fact thatthe post 16, which is part of said shaft, is vertically movable in the'passage 14 in the arm 13, and the spring 22 tends to hold the shaft inthe uppermost position so that the belt 31 connecting the pulleys 26 and12 is always kept tight. The engagement of the face 18 on the headprovided on the end of the shaft 17 with the vertical face 15 on the arm13 keeps the shaft fromtwisting from one side to the other, and insuresa broad bearing surface for the end thereof, so that it is compelled tomove vertically and cannot twist or turn in the horizontal plane. Thespring 22 allows a downward movement of the post 16 and the shaft so asto permit the easy removal of the fan belt whenever that is desired,and, as has been stated above, the spring 22 always keeps the fan belttight and prevents its becoming slack, so as to prevent any trouble orannoyance on that account.

I am aware that the particular embodiment of my invention which I havehere shown and described, is susceptible of con siderable variationwithout departing from the spirit of my invention, but I have found thatthis particular embodiment is desirable from many standpoints, and,therefore, I desire to claim the same specifically as well as broadly,as indicated by the" appended claims.
